Answer:

341.25

Step-by-step explanation:

You first split the figure into 2 pieces the triangular prism and the rectangular prism now that we know the dimensions of each figure we can create an expression, we will start with the triangular prism. the expression will be 3/2 x 5/2 x 10.5. Then we solve the rectangular prism. 5 x 5 x 10.5.

Now that we have acquired all the math that we need we can continue to simplify. 3 x 2 x 5/2 was derived from (3 x 5)/2 and we physically drew it out with properties of algebra (a later topic to study) anyways we get 15/2=7.5 and we multiply that by 10.5 giving us 78.75. the triangular prism is easier we just do 25 x 10.5 giving us 262.5. Now that we have succumbed both figures we can combine the to get the volume which is 341.25 (78.75 + 262.5).

Work hours = 28 hours

Earning = $8 per hour

1 hour = $8

28 hours = $8 × 28

28 hours = $224

He has earned $224 last month.

Answer:

Hence, slope of y=7x−2 is 7 and y -intercept is −2.

Step-by-step explanation:

The equation of any straight line can be written as y=mx+c, where m is its slope and c is its y-intercept.

Comparing the equation y=7x−2 with the standard form of the equation, we get:

m=7,c=−2

Hence, slope of y=7x−2 is 7  and y -intercept is −2

Step-by-step explanation:

The graph is misleading because the vertical scale does not start at zero.

To better represent the brand relationship, the vertical axis should start at zero. The amounts differ by less than 1/2%, so the bars on that scale would appear to have virtually identical heights.

Answer:

y = -x – 2

Step-by-step explanation:

Slope is ΔY/ΔX =  -1

plug this into the equation:

1=-(-3) +b

= -2=b

so we get; y = -x – 2

Answer: y = -x - 2

Step-by-step explanation:

     I will be writing this equation in slope-intercept form.

     First, we will find our m value, also known as the slope.

        [tex]\displaystyle \frac{\text{change in y}}{\text{change in x}} =\frac{1--4}{-3-2} =\frac{5}{-5}=-1[/tex]

     Now, we will find our b value, or the y-intercept.

-> The line intercepts the y-axis at (0, -2), so our y-intercept is -2.

     Lastly, we will write our equation.

y = mx + b

y = -x - 2

There are total 15 dogs, 27 cats, and 3 ferrets were adopted if the ratio of dogs to ferrets was 5:1. The ratio of cats to dogs was 9:5.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

An animal shelter had 45 animals adopted over one week. The ratio of dogs to ferrets was 5:1. The ratio of cats to dogs was 9:5.

Combine ratio dogs:ferrets:cats = 5:1:9

Let's suppose the number of ferrets is x then:

5x + x + 9x = 45

15x = 45

x = 3

Ferrets x = 3

Dogs = 5x = 5(3) = 15

Cats = 9x = 9(3) = 27

Thus, there are total 15 dogs, 27 cats, and 3 ferrets were adopted if the ratio of dogs to ferrets was 5:1. The ratio of cats to dogs was 9:5.

Answer:

C- 17 cm

A- 9cm

Step-by-step explanation:

C - because plus 9 and 8 is 17 cm

A - because plus 4 and 5 is 9 cm

Answer:

(x - 6)(x - 3)

Step-by-step explanation:

x² - 9x + 18

consider the factors of the constant term (+ 18) which sum to give the coefficient if the x- term (- 9 )

the factors are - 6 and - 3 , since

- 6 × - 3 = + 18 and - 6 - 3 = - 9 , then

x² - 9x + 18 = (x - 6)(x - 3) ← in factored form

Answer:

(x - 3)(x - 6)

Step-by-step explanation:

x²- 9x+18

= x^2 - 6x - 3x + 18

= x(x - 6) - 3(x - 6)

= (x - 3)(x - 6).

The total cost of the Job in the question is; D: $87,500

We are given that;

Direct Labor = $25000

Cost of direct materials used = $50000

Overhead is 50% of direct labor costs. Thus;

Overhead Cost = 50% * $25000 = $12500

Total Cost of Job = Overhead Cost + Materials Cost + Labor Cost

Answer: The range of the data set is: " 16 " .

______

Explanation:
The range is calculated by subtracting the lowest value in the given data set from the highest value in the data set.
______

Given: The data set:   9, 21, 7, 11, 13, 21, 5, 14 ;

Let us organize these numbers from lowest value to highest value:
  " 5, 7, 9, 11, 13, 14, 21, 21 " ;
Note:  This is done by inspection.  Note that all eight (8) values are accounted for.
    So, we subtract the lowest value in our given data set:  "5" ;

from the highest value in our given data set:  "21" ;  to get the "range":

            →  " 21 − 5 = 16 " ;

If the probability will be 0.7842. Then the number of students who scored between 200 and 245 will be 941.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The scores of a recent test taken by 1200 students had an approximately normal distribution with a mean of 225 and a standard deviation of 18.

Then the number of students who scored between 200 and 245 will be

Then the z-score for x = 200

[tex]z = \dfrac{200-225}{18}\\\\z = -1.389[/tex]

Then the z-score for x = 245

[tex]z = \dfrac{245-225}{18}\\\\z = 1.1111[/tex]

Then we have

[tex]\begin{aligned} P(-1.39 < z < 1.11) &= P(z < 1.11) - P(z < -1.389)\\\\&= P(z < 1.11)- [1-P(z > -1.389)] \\\\&=0.8665 - (1-0.9177) \\\\&=0.7842 \end[/tex]

Then the number of students who scored between 200 and 245 will be

→ 0.7842 × 1200

Answer:

5/6-1/9=45/54-6/54=39/54.

Step-by-step explanation:

hey!

To make fractions have a common denominator, multiply both the numerator and denominator by the same number. For example, 5/6=45/54 because I multiplied 5 and 6 both by 9, and 1/9= 6/54 because I multiplied 1 and 9 by 6. This is the same for all fractions.

Answer:

13/18

Reasoning:

First. We have to find the GCD

Second. Multiply both fractions with the number that creates the GCD

5/6 x 3/3 - 1/9 x 2/2 = 15/18 - 2/18

Third. Subtract 15/18 - 2/18 = 13/18

The roots of the equation [tex]x^{2}[/tex]-15x +2 =0 are 14.865 and 0.135

Completing the square method is one of the methods to find the roots of the given quadratic equation.

Given equation is:

[tex]x^{2}[/tex]-15x +2 =0

Using Completing the Square method we have

[tex]x^{2}[/tex]-15x +2 + [tex](\frac{15}{2})^{2}[/tex] - [tex](\frac{15}{2})^{2}[/tex] =0

Now,

[tex]x^{2}[/tex]-15x + [tex](\frac{15}{2})^{2}[/tex] - [tex](\frac{15}{2})^{2}[/tex] +2=0

or, [tex][x-(\frac{15}{2})]^{2}[/tex] - 225/4 +2 =0

or,  [tex][x-(\frac{15}{2})]^{2}[/tex] -217*4 =0

or,  [tex][x-(\frac{15}{2})]^{2}[/tex] = 217/4

or,  [tex]x[/tex] = [tex]\pm \frac{14.73}{2} + \frac{15}{2}[/tex]

or, [tex]x_1[/tex]= 14.865, [tex]x_2[/tex]= 0.135
